A Note on Hayman's Problem and the Sharing Value
该文主要讨论Hayman的一个问题与分担值的联系,并运用新颖的方法证明了:设f 为非常数的整函数,n,k均为正整数,n≥k+1,a为非零的有穷复数,若a为f^n与(f^n)^(k)的分担值,则nf′=ωf,ω为方程t^k=1的根.

Let f(z) be a nonconstant entire function, n be a positive integer grea ter than one, and a be a nonzero finite complex number. If f^n and (f^n)^(k) share a, then nf′=ωf, where ω is the root of equation t^k=1.
